PLOW.

SPECIFICATION forming part of- Letters Patent No. 277,185, dated May 8, 1883.

Application filed March 27, 1B S3. (No model.)

To all whom it may concern Be it known that 1, CHARLES ANDERSON,

of South Bend, in the county of St. Joseph and My invention relates to an improvement in that class of wings for plows which are adapted to be reversed edge for edge and face for face, the object being to produce articles of this character which shall combine simplicity and cheapness of construction with durability and efficiency in use, and which shall obviate the objections inherent'in the wings now on the market.

Heretofore reversible wings of the character designated havegrb'een constructed to make that one of the working-faces not in action fulfill the function'of a bearing for supporting the other face in its proper position with respect to the mold-board. During the process of manufacture alarge percentage of the wings are more or less distorteda defect which must be remediedfif at all, by reducing them to the required shape by grinding; but here a difficulty arises, for by grinding the working-faces of the wings to conform them to the lines of the mold-board they are uufitted for performing their hearing function, as described. Neither can the distortion of the wings be remedied by grinding or reshaping the mold-hoards to conform to' them, for when the same is ground to conformity with one face of a wing it will obviously not conform to the other face thereof. It is apparent, therefore, that almost absolute perfection of shape and'finish is necessary, not only in the wings, but also in the plows, to enable the former to be reversed and to be used in duplicate, such exactness of construction requiring skilled labor, and rendering plows provided with reversible wings very and must be discarded. Again, the prevailing styles of reversible wings necessarily entail in their attachment to the mold-board the formation of bold lines or contours, which interfere with the operation of the plow.

With the end in view of obviating the Objl ctions above recited, my invention consists in certain details of construction and combina- 6o tions of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1' is a view in perspective ofa plow adapted to receive and provided witha wing constructed in 6 accordance with my invention. Fig. 2 is a similar view of the plow with the reversible wing'removed. Figs. 3 and 4 respectively are reverse planviews of the plow with the wing in place and removed. Fig. 5 is a view 0 showing both faces of the reversible wing; and Fig. 6 is a plan view, showing one of the modified forms which the wing may assume.

- The lower portion of the mold-board'A and the rear portion of the reversible point B are ap- 7 5 propriately cut away to expose the plow-standard G,to which they are respectively attached. By cutting away the mold-board and point, as described, a recess is formed, which receives one end of the reversible wing, the other end thereof extending rcarwardly under the heel of the mold-board, as shown in Fig.1 of the drawings. The said reversible wing, which is preferably formed in one piece, consists, essentially,

of two triangular working-faces, D, placed back 8 5 to back, and arranged to cross each other diag onally, as illustrated. The said working-faces are defined apart by ledges E, which coincide with the lower edge, F, of the mold-board,whilethe bases G of the wings coincide with the edges I of the reversible point B. That portion of the base or rear face of each of the workin g-faces D which is not occupied by the crossing-point of the other face constitutes a bearing, J When .the wing is in working adjustment, and irre-v spective of the working-face exposed, the'said bearings respectively rest upon the exposed portion of the standard 0 and the point B and upon the brace K, interposed between themoldboard and the landside L, the said standard beme N, respectively passing through the mold board, the brace, and one working-face, and through the other working-face and the standard, a very firm seat for the wing and a solid combination of parts being thus obtained. In virtue of the triangular shape of the workingfaces D, the extent of surface exposed to direct friction is greatly reduced. Again, in virtueof the described shape of the workingfaces and of their relative arrangement with respect to the mold-board, the heel of the latter may be extended as low and shaped as desired to best adapt the plow to the character of the soil and to the use to which it is to be made subservient. In virtue, also, of the construction of the wing and of the adaptation of the plow to receive it, thebearings of both the wing and the plow are protected from wear, and so long as these bearings hear an unchanged relationship to each other the wings can be reversed and replaced in duplicate.

As already referred to, the prevailing styles of reversible wings necessarily entail, in their attachment to the mold-board, the formation of bold lines or contours, which interfere with the operation of the-plow, whereas with my plow and wing the working-faces of the latter may be suitably concaved or otherwise conformed to the lines of the mold-board in such manner that the lines of the two parts will shade into each other perfectly, and this without interfering with variation in the lines of the mold-board to adapt it to'diiferent kinds of work.

Iron, steel, or other suitable material is employed in the fabrication. of my improved wings, which are preferably formed by casting,

the operation of finishing them consisting es-- sentiallyin first grinding them to fit the edges of the mold-board and point, and then attaching them in both positions to a model plow and grinding and polishing their workingfaces until the same have the desired contour with respect to its mold-board.

From the foregoing it will be seeuthat the improved wings, being comparatively simple to manufacture and requiring no more metal than the prevailing styles, may be supplied to the trade at reduced rates.

Although the wing and point have been described as being independent of each other,

" they may, if desired, be made in one piece, as

shown in Fig. 6 of the drawings.

I would have it understood that I do not limit myself to the exact construction shown and described, but hold myself at liberty to make such changes and alterations as fairly fall within the, spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A reversible wing for plows, consisting, essentially, of two working-faces placed back to back and crossing each other diagonally.

2. A reversible wing for plows, consisting, essentially, of two working-faces placed back to back, and crossing each other diagonally and defined apart by ledges.-

3. A reversible wing for plows, consisting, essentially, of two working-faces placed back to back and .crossing each other diagonally, the rear face of the outer end of each workingface being provided with hearing to support the wing on the plow.

4. A reversible wing for plows, consisting, essentially, of two working-faces triangular in general outline, and conformed in facial contour to the lines of the mold-board, said faces being placed back to back and crossing each other diagonally.

5. The combinatiomwith a plow, of a reversible wing consisting, essentially, of two working-faces placed-back to back and provided with bearings, the bearingof one face resting upon the standard of the plow, and that oftheother face-on a support located under the mold-board, substantially as set forth.

6. The combination, with 'aplow provided with a mold-board, the lower portion of which is cut away, as described, of areversible wing havingworking faces of.triangular outline placed back to back, said wing being adjusted to the mold-board in the manner shown, substantially as set forth.

7. The combinatiomwith a plow provided with a mold-board, the lower portion of which is cut away to expose thestandard of. the plow, and-with a brace, the same being interposed between the landside and mold-board,of a reversible wing having two working-faces of triangular outline and placed back tobaek,-

and provided with bearings, the bearing of one face resting upon the exposed portion of the standard, and that of thei other face upon the said brace, substantially "as set forth.

8. The combination, witha plow provided with a mold-board, the lower portion of which is cut away, as described, and with a reversible point, the rear portion of which is cut IIO away flush with the standard, of a reversible wing consisting, essentially, of two workingfaces placed back to back and provided with bearings, the bearing of one face resting on the exposed portion of the standard and the rear of the reversible point, and that of the other face on a support located beneath the mold-board, substantially as set forth.

9. The combination, with a plow provided with a mold-board, the lower portion of Which is cut away to expose the standard, the edge IIS of the same being flanged, of a reversible wing consisting, essentially, of two working-faces placed back to back and defined apart by ledges, as described, the ledge of the face not in action having bearing in the flange of the standard, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
